Obesity is associated with IL-6 gene polymorphisms rs1800795 and rs1800796 but not SOCS3 rs4969170.

Background: An imbalance of inflammatory factors can stimulate obesity by inducing chronic inflammation in adipose tissue. Interleukin-6 (IL-6) is a cytokine with both inflammatory and anti-inflammatory functions. Suppressor of cytokine signaling 3 (SOCS3) acts as an inhibitor for a number of cytokine signals.

TAS1R2 rs35874116 and TRPM5 rs886277 polymorphisms are not related with risk of obesity.

Objectives: Obesity is one of the most serious public health problems due to its high morbidity and mortality rates. The taste perception is a powerful factor affecting food acceptance and may be one of the causes of tendency to obesity. Genetic variations in TAS1R2 and TRPM5 genes that affect taste preferences may cause inter-individual differences in food selection and thus increase the risk of obesity.

Association of aryl hydrocarbon receptor (AhR) serum level and gene rs10247158 polymorphism with anthropometric, biochemical parameters and food consumption in overweight/obese patients.

Aim: Aryl hydrocarbon receptor (AhR) plays a role in xenobiotic metabolism, which can be also activated by dietary patterns and components. AhR ligands in circulation are reported to induce weight gain, glucose intolerance and suggested to contribute to the development of obesity. In this study, we aimed to examine the relationship of the AhR gene and its polymorphisms with obesity and food consumption.

Investigation of Aryl Hydrocarbon Receptor, Zinc, and Vitamin B12 Levels in Chronic Gastritis with Helicobacter pylori Infection.

Helicobacter pylori (H. pylori) infection is known as the most common cause of worldwide common chronic gastritis. Pathogenic mechanisms caused by H.

Male infertility in Sertoli cell-only syndrome: An investigation of autosomal gene defects.

Objectives: To detect autosomal genetic defects and to determine candidate genes in Sertoli cell-only syndrome infertile men.

Methods: Single-nucleotide polymorphism + comparative genomic hybridization microarray technology was carried out on 39 Sertoli cell-only syndrome infertile patients in the present study. Array comparative genomic hybridization compares the patient's genome against a reference genome, and identifies uncover deletions, amplifications and loss of heterozygosity.

Investigation of the association between mitochondrial DNA and gene mutations in transitional cell carcinoma of the bladder.

Bladder carcinoma is the most common malignancy of the urinary tract. The major aim of the present study is to investigate the association between mitochondrial DNA () and gene mutations in bladder carcinoma. A total of 30 patients with transitional cell carcinoma and 27 controls were recruited for the study.

The frequency and the effects of 21-hydroxylase gene defects in congenital adrenal hyperplasia patients.

Congenital adrenal hyperplasia (CAH) is a group of genetic endocrine disorders, caused by enzyme deficiencies in the conversion of cholesterol to cortisol. More than 90% of the cases have 21-hydroxylase deficiency (21-OHD). The clinical phenotype of the disease is classified as classic, the severe form, and nonclassic, the mild form.

Detection of mitochondrial DNA mutations in nonmuscle invasive bladder cancer.

Background: Mitochondrial DNA (mtDNA) mutations have been recently described in various tumors; however, data focusing on bladder cancer are scarce. To understand the significance of mtDNA mutations in bladder cancer development, we investigated the mtDNA alterations in bladder cancer cases.

Methods: We studied the mtDNA in 38 bladder tumors and 21 microdissected normal bladder tissue samples.
